1b (/77 grhmii i'f-mny mime/ n Be it known that I, ALFRED G. F. KURowski. a citizen of the United States, residing in New York city, borough of Bronx, in the county of New York and State of New York. have invented certain new and useful Improvements in Type-Writing Machines of which the following is a specificat on.

v This invention relates to tally sheet feed ing mechanisms for t-ypewriting machines employed for billing and analogous purposes, wherein the amounts of a succession of bills or the like which are written on the machine, are entered upon tally sheets fed iiuermittently around the platen.

()ne of the main objects is to provide an improved and simplified device associated with the usual sheet-feeding mechanism for "mechanically feeding strips of paper (su'ch as individual tally sheets) around the platen independently of the usual paper feeding mechanism. and one which is easily applied I to existing machines. The usual cylindrical are-1- appear.

separable to platen having feed rolls which are cast off and restored thereto at will, is provided with a tally-sheet feeding mechanism comprising a feeding couple of rolls hieated near one end of the platen, to feed the tally sheets around the platen independently of the platen-feed rolls. The feeding couple is operated through a line-space wheel and pawl actuated by the main feed-roll release mechanism. so as to advance the tally sheet. as the 'main feed rolls are cast oil. The feed couple is located just above the-printing line and closely adjacent the platen, so that comparas tirely short strips may be accommodated.

The rolls comprising the feed couple are leading edges of the sheets. \Vhen printed tally forms are used, it is desirable that the entries fall upon the ruled lines, to effect which the leading edge of the'tally sheet is gaged or set to a predetermined point, so that the first line of writing will fall upon the desired ruled line. For this purpose a gage is moved into the path of the tally sheet as the feeding couple is opened; and after the couple is closed the gage -1s displaced to avoid obstructing the sheets.

()ther-objectlg and advantages will herein- In the accompanying drawings, Figure l is a perspective view of the platen frame of an Underwood typewritmgniachine, show,

afford easy insertion of the inguny invention applied thereto. Fig. 2 is across sectional view showing the parts in normal position. Fig. 3 is a similar View showing the rolls of the feeding couple separated for the introduction of the leading edge of the tally sheet, the gage or aliner beingin efi'ective position. Fig. at is an enlarged view similar to Fig. 2, parts being removed to better disclose the construct-ion. Fig.- 5 is a detailperspective view of the ratchet or line-space Wheel'for turning the feeding couple. Fig. 6 is a top plan view; parts being broken away-to better disclose the device. Fig. 7 is a detail sectional View taken on line w-w of Fig. .6 andlooking in the direction of the arrow, the parts being in normal position. Fig. 8 is a similar view showing the rolls of the feeding couple separated. Fig. 9 is a detail viewshowing the connection between the release key and the cam shaft.

Types 1 strike upon the front of a platen rolls are cast off from and restored to the platen by a release key 8 which operates a crank 9 and link 10 to turn a cam shaft 11,

and rock lugs 12 connected with the roll-' supporting arms 13. The link 10 is pivoted at its lower end to crank-arm ll on shaft 11. The series of main feed rolls 6, 7 does not extend entirely across the platen, and that end thereof which is unoccupied by the main feed rolls has a tally sheet feeding mechanism. l

- The tally sheet 14 is machine by being dropped into the throat introduced into the between the paper shelf 5 and the rear face of the platen 2.. Side gages 15 adjustable on the paper shelf may be used to guide the tally sheet. The leading edge of the tally sheet passes freely around beneath the platen owing to the absence of the platen rolls 6, 7 at that end, and rises in front of the platen, and up past the printing line.- The leading ed e of the tally sheetis inserted between re s 16, l7 forming a feeding couple loouted just abuse the printing line. The base be journaled in a stationary bracket 19 we V mounted to turn in arms 21. 21* journaled the leading edge of the work sheet and the angle slot in an extension 32 of one of the arms 21, 21 are rigidly connected by hollow 'lies behind the feeding couple out of the to maintain the cam in effective position against the tension of a returnlng spring 45 roll 16 of the feeding couple is mounted on a shaft 18, the left-hand end of which may tending forwardly from the usual platenframe rod 20, the opposite end of the shaft being conveniently journaled in the adjacent end 3 of the platen frame. The roll 17 is by means of a hub or hollow shaft 21" on the rod 20. A spring 22 normally holds the roll 17 against roll 16 to gripthe sheet. A finger piece 25 turns a cam 23journaled on a stud 24, to engage one of the arms 21 supporting 1011 17, to move the latter away from roll 16, Fig. 8. For this purpose the It is desirable'to aline or square the leading edge of the sheet prior to closing the feeding couple on the paper, so that the entries may be written on theruled lines of a form, the distance between the printing line and the gage with which the leading edge is squared agreeing with the distance between first ruled line'thereon. For this purpose, a gage 26 may be journale by a pair of ears 27 on the base roll shaft 18, and'normally path of the sheet (see Figs. 4:, 6 and 7). The gage comprises a plate having a propiece 25 is rocked to release the rolls, it also swings an arm 29, which has a stud 30 to engage a shoulder 30 forming one side of an hinge ears or arms 27'upon which the gage turns. The gage is thus moved to operative position, in the path of the leading edge of the tally strip, and is held by a spring (Fig. 6) against a stop 34 on arm 19. It will be seen that it is when the gage has reached its operative position that the cam 23 engages the roll controlling arm 21 to raise the pressure roll 17, the stud 30 meanwhile idly traversing a dead portion 31 of the slot in the extension 32. The friction be-. tween the cam and the arm 21 is sufiicient connected with the cam by an arm 46. The operator'can hence use both hands to adjust the tally sheet. The sheet is held by the operator against the gage, while the finger piece 25 is returned to restore the pressure roll 17. As the finger piece-returns to normal position, the cam 23 first releases the I Oll-COIltIOlllDg arm 21*, which is returned by its spring 22 and causes the pressure roll 17 to clamp the sheet. The stud 30 moves idly down the slot portion 31 while the pressure roll 17 is returning, after whichsaid stud engages the end -wa1l.31 of the slot to return the age to inoperative position. 1 By thus clamping the tally sheet before returning the gage, the sheet is prevented from becoming displaced. The returning spring 45 overcomes the gage-operating spring to normally hold the gage inoperative.

The tally sheet 14 is fed through regular intervals by a line-spacemechanism connected preferably with the'base roll 18. The shaft 16 of the base roll has a lino-space wheel 35, the lateral teeth 36 of which (Fig.

5) are engaged by a pawl 37 recessed at its free end, as at 38, Fig. 1, to engage the teeth, and having a: spring 40. The pawl 37 is pivoted to crank 11" of rock-shaft 11. When the latter is rocked and the platen rolls 6, 7 are castoff to permit the removal of a completed bill andthe insertion of a fresh one, the tally sheet is line-spaced for anew entry or line of Writing A detent 41, pivoted at 42, has a tooth 43 setting'into reoesses 44 in the periphery of the wheel 35. Conveniently the returning spring 45 may actuate the detent.

Variations may be resorted to within the scope of the invention, and portions of the improvements may be used without others.
